About slurry product(Wet powder)

The cosmetic color powder(foundation and eye shadow) need to be mixed with solvent (IPA, ethanol, isoparaffin, water and so on), to make it slurry state like mayonnaise.
This slurry is filled in the pan from top or back with single color or multi color in the same time.
In the moment of press, the solvent is sucked from upper mold. After that, the product needs the drying process.
About 80 % of the eye shadow product from cosmetics manufacture in Japan is produced by slurry process, because of its good quality.

Feature of the slurry product

Less hardness difference
Easier to press the powder which has much pearl
The product become looseness(such as sponge state), so the touch feeling is much better and smooth.
The small powder piece on the edge of pan is much less, so this small powder piece doesn't fall down in the product shipment.
Good environment for operator regarding powder dust exposure, because powder dust doesn't fly in the air(because of slurry).

Product feature and productivity of BIM(back filling)

The slurry is filled in the pan with the pressure from back side of the pan.
The solvent is sucked from upper mold through the paper and cloth(screen).
And final press is necessary according to the powder formula and design.

Good for small size of the pan and multi-cavity, and also multi color, so normally used for eye shadow product.
Possible to fill sharp and narrow area with less hardness difference, which is impossible for dry powder.
Possible to produce doom shape, because the slurry is filled with pressure.
It is possible to reduce the cost for the pan, mold of the pan and assembly process, as compared with powder press product,because it is possible to fill several color in the same time in the pan.
Possible to reduce pan clean up process, because powder doesn't put on the out side of the pan, except around filling hole.
The pan needs to have hole in the backside of the pan to fill slurry.

Product feature and productivity of top filling

The slurry is filled from the top side of the pan with every time same quantity.
The first press and final press is necessary to suck the solvent through the paper and cloth.

It is possible to fill slurry in short time, so normally used for foundation which needs much powder quantity, and also used for face color with multi color.
In the case of the multi color with top filling, it is less cost than dry powder press.
It is unnecessary to make the hole on the back side of the pan, and possible to use both aluminum and plastic pan.

The point of slurry filling machine selection for industrial type

Slurry filling machine rotary type is recommendation, if you would like to produce BIM (back filling) product with single or multi color.
In case of multi color, the pan must have partition inside of it.
Slurry filling machine line type is recommendation, if you need versatile function which can produce BIM product and top filling product.

For example, in case of BIM, it is possible to produce 32 pcs/min, 4 color eyeshadow.
*Pan size less than 30mm x 70mm, Filling time is less than 4 sec.
All setting parameter which has influence on the product quality is from touch panel, and it is possible to save and read out these setting parameters.
The servo motor is used for filling pump. This servo motor is controlled by 2 system, one is the torque control(pressure filling) for back filling(BIM), and the other is position control(same amount filling) for top filling.
It is possible to set the filling amount, filling pressure, filling speed for each pump or each color.
The servo motor is used for upper mold up/down movement in press unit. For the press, the upper mold goes down with high speed with position control to reduce free running time, and the servo motor control is switched to torque control for press, so it is possible to reduce the time for press
The actual pressure to the powder in the moment of the press is indicated in the screen every time, so it is possible to monitor the relation and clearance between upper mold and pan, and if the machine is running appropriately or not, too.
In case of top filling, the special figure of the upper mold is used in the first press, to avoid leaking the slurry goes outside the pan.
If the increased safety is required for the explosion-proof, inside of the electric box is pressurized by the air to avoid the flammable gas go inside of the electric box.
This air pressure which supplies in the electric box is detected by the sensor, in the case of this pressure is lower than appropriate pressure, the electric power supply will be shut down.

It is possible to reduce the time for mold change, because number of the mold is less, and due to smaller machine size.
It is possible to reduce the number of the operator, with using the pan supply feeder which is option.
All setting parameter which has influence on the product quality is from touch panel, and it is possible to save and read out these setting parameters.

This servo motor is controlled by 2 system, one is the torque control(pressure filling) for back filling(BIM), and the other is position control(same amount filling) for top filling.

The mold (Vacuum pad and BIM filling unit except BIM filling nozzle) is possible to use combinedly with industrial machine.

It is possible to set the filling amount, filling pressure, filling speed for each pump or each color.

The actual pressure to the powder in the moment of first and second press, and filling pressure in case of the BIM is indicated with graphic on the monitor, because press unit has the load cell.
Adjustment of the press pressure, BIM filling pressure and vacuum pressure is from regulator.
The parameter setting of Press time, BIM filling time, Vacuum time and so on is from operation panel.
Switch the vacuum pad is by handle manually, between vacuum pad for BIM/first press and second press.
